Method and system for attribute extraction from product titles using sequence labeling algorithms

ABSTRACT

A system and method for attribute extraction from product titles is presented. A set of product titles are read by an embodiment. The product titles are separated into a sequence of tokens, the tokens being determined by the presence of a separator character. The sequences of tokens are labeled according to a specific encoding scheme to denote attributes of a title, such as brand name and other features. The characteristics of the attributes within the title are determined to build a sequence labeling algorithm. The results of the encoding is compared to a normalization dictionary comparing standardized attributes. A blacklist can be consulted to further refine the method. A further validation can be performed to catch any remaining mistakes. Thereafter, a database entry can be made to associate the attribute with the item. A training set can be used to initialize the learning model. Other embodiments are also disclosed herein.

TECHNICAL FIELD

This disclosure relates generally to on-line retail sales and more particularly to a method and system for extracting attributes from product titles in an electronic commerce environment.

BACKGROUND

An electronic commerce (“eCommerce”) provider will typically maintain a website and/or a mobile app that allows customers to search and browse through the eCommerce provider's goods and services. It can be desirable for the eCommerce provider to allow the user to search and filter items based on characteristics of the items. It can be desirable for the eCommerce provider to have an automated method of determining characteristics of the items it sells.

Skipping ahead now in the drawings, FIG. 3 illustrates a representative block diagram of a system 300, according to an embodiment. System 300 is merely exemplary and embodiments of the system are not limited to the embodiments presented herein. System 300 can be employed in many different embodiments or examples not specifically depicted or described herein. In some embodiments, certain elements or modules of system 300 can perform various methods and/or activities of those methods. In these or other embodiments, the methods and/or the activities of the methods can be performed by other suitable elements or modules of system 300.

As further described in greater detail below, in these or other embodiments, system 300 can proactively (e.g., prospectively) and/or reactively (e.g., responsively) determine and/or communicate the consumer product information to the consumer, as desired. Proactive acts can refer to acts (e.g., identification, determination, communication, etc.) performed without consideration of one or more predetermined acts performed by the consumer; and reactive acts can refer to acts (e.g., identification, determination, communication, etc.) performed with consideration of (i.e., in response to) one or more predetermined acts performed by the consumer. For example, in some embodiments, the predetermined act(s) can comprise an act of identifying a selection of a consumer product by the consumer.

Meanwhile, as also described in greater detail below, system 300 can be implemented in brick-and-mortar commerce and/or electronic commerce applications, as desirable. Further, in many of these or other embodiments, system 300 can communicate the consumer product information to the consumer substantially in real-time (e.g., near real-time). Near real-time can mean real-time less a time delay for processing (e.g., determining) and/or transmitting the relevant consumer product information to the relevant consumer. The particular time delay can vary depending on the type and/or amount of the consumer product information, the processing speed(s) of the processing module(s) of system 300, the transmission capability of the communication hardware (as introduced below), the transmission distance, etc. However, in many embodiments, the time delay can be less than approximately one, five, ten, or twenty minutes.

Generally, therefore, system 300 can be implemented with hardware and/or software, as described herein. In some embodiments, part or all of the hardware and/or software can be conventional, while in these or other embodiments, part or all of the hardware and/or software can be customized (e.g., optimized) for implementing part or all of the functionality of system 300 described herein.

Specifically, system 300 comprises a central computer system 301. In many embodiments, central computer system 301 can be similar or identical to computer system 100 (FIG. 1). Accordingly, central computer system 301 can comprise one or more processing modules and one or more memory storage modules (e.g., one or more non-transitory memory storage modules). In these or other embodiments, the processing module(s) and/or the memory storage module(s) can be similar or identical to the processing module(s) and/or memory storage module(s) (e.g., non-transitory memory storage modules) described above with respect to computer system 100 (FIG. 1). In some embodiments, central computer system 301 can comprise a single computer or server, but in many embodiments, central computer system 301 comprises a cluster or collection of computers or servers and/or a cloud of computers or servers. Meanwhile, central computer system 301 can comprise one or more input devices (e.g., one or more keyboards, one or more keypads, one or more pointing devices such as a computer mouse or computer mice, one or more touchscreen displays, etc.), and/or can comprise one or more display devices (e.g., one or more monitors, one or more touchscreen displays, etc.). In these or other embodiments, one or more of the input device(s) can be similar or identical to keyboard 104 (FIG. 1) and/or a mouse 110 (FIG. 1). Further, one or more of the display device(s) can be similar or identical to monitor 106 (FIG. 1) and/or screen 108 (FIG. 1). The input device(s) and the display device(s) can be coupled to the processing module(s) and/or the memory storage module(s) of central computer system 301 in a wired manner and/or a wireless manner, and the coupling can be direct and/or indirect, as well as locally and/or remotely. As an example of an indirect manner (which may or may not also be a remote manner), a keyboard-video-mouse (KVM) switch can be used to couple the input device(s) and the display device(s) to the processing module(s) and/or the memory storage module(s). In some embodiments, the KVM switch also can be part of central computer system 301. In a similar manner, the processing module(s) and the memory storage module(s) can be local and/or remote to each other.

In many embodiments, central computer system 301 is configured to communicate with one or more consumer computer systems 302 (e.g., a consumer computer system 303) of one or more consumers. For example, the consumer(s) can interface (e.g., interact) with central computer system 301, and vice versa, via consumer computer system(s) 302 (e.g., consumer computer system 303). Accordingly, in many embodiments, central computer system 301 can refer to a back end of system 300 operated by an operator and/or administrator of system 300, and consumer computer system(s) 302 can refer to a front end of system 300 used by one or more users of system 300 (i.e., the consumer(s)). In these or other embodiments, the operator and/or administrator of system 300 can manage central computer system 301, the processing module(s) of computer system 301, and/or the memory storage module(s) of computer system 301 using the input device(s) and/or display device(s) of central computer system 301. In some embodiments, system 300 can comprise consumer computer system(s) 302 (e.g., consumer computer system 303).

Like central computer system 301, consumer computer system(s) 302 each can be similar or identical to computer system 100 (FIG. 1), and in many embodiments, each of consumer computer system(s) 302 can be similar or identical to each other. In many embodiments, consumer computer system(s) 302 can comprise one or more desktop computer devices, one or more wearable user computer devices, and/or one or more mobile devices, etc. At least part of central computer system 301 can be located remotely from consumer computer system(s) 302.

In some embodiments, a mobile device can refer to a portable electronic device (e.g., an electronic device easily conveyable by hand by a person of average size) with the capability to present audio and/or visual data (e.g., images, videos, music, etc.). For example, a mobile device can comprise at least one of a digital media player, a cellular telephone (e.g., a smartphone), a personal digital assistant, a handheld digital computer device (e.g., a tablet personal computer device), a laptop computer device (e.g., a notebook computer device, a netbook computer device), a wearable user computer device, or another portable computer device with the capability to present audio and/or visual data (e.g., images, videos, music, etc.). Thus, in many examples, a mobile device can comprise a volume and/or weight sufficiently small as to permit the mobile device to be easily conveyable by hand. For examples, in some embodiments, a mobile device can occupy a volume of less than or equal to approximately 189 cubic centimeters, 244 cubic centimeters, 1790 cubic centimeters, 2434 cubic centimeters, 2876 cubic centimeters, 4056 cubic centimeters, and/or 5752 cubic centimeters. Further, in these embodiments, a mobile device can weigh less than or equal to 3.24 Newtons, 4.35 Newtons, 15.6 Newtons, 17.8 Newtons, 22.3 Newtons, 31.2 Newtons, and/or 44.5 Newtons.

Exemplary mobile devices can comprise, but are not limited to, one of the following: (i) an iPod®, iPhone®, iPod Touch®, iPad®, MacBook® or similar product by Apple Inc. of Cupertino, Calif., United States of America, (ii) a Blackberry® or similar product by Research in Motion (RIM) of Waterloo, Ontario, Canada, (iii) a Lumia®, Surface Pro™, or similar product by the Microsoft Corporation of Redmond, Wash., United States of America, and/or (iv) a Galaxy™, Galaxy Tab™, Note™, or similar product by the Samsung Group of Samsung Town, Seoul, South Korea. Further, in the same or different embodiments, a mobile device can comprise an electronic device configured to implement one or more of (i) the iOS™ operating system by Apple Inc. of Cupertino, Calif., United States of America, (ii) the Blackberry® operating system by Research In Motion (RIM) of Waterloo, Ontario, Canada, (iii) the Palm® operating system by Palm, Inc. of Sunnyvale, Calif., United States, (iv) the Android™ operating system developed by Google, Inc. of Mountain View, Calif., United States, (v) the Windows Mobile™, Windows Phone™ and Windows 10 (mobile)™ operating systems by Microsoft Corporation of Redmond, Wash., United States of America, or (vi) the Symbian™ operating system by Nokia Corp. of Keilaniemi, Espoo, Finland.

In further embodiments, central computer system 301 can be configured to communicate with software (e.g., one or more web browsers, one or more mobile software applications, etc.) of the consumer computer system(s) 302 (e.g., consumer computer system 303). For example, the software can run on one or more processing modules and can be stored on one or more memory storage modules (e.g., one or more non-transitory memory storage modules) of the consumer computer system(s) 302 (e.g., consumer computer system 303). In these or other embodiments, the processing module(s) of the consumer computer system(s) 302 (e.g., consumer computer system 303) can be similar or identical to the processing module(s) described above with respect to computer system 100 (FIG. 1). Further, the memory storage module(s) (e.g., non-transitory memory storage modules) of the consumer computer system(s) 302 (e.g., consumer computer system 303) can be similar or identical to the memory storage module(s) (e.g., non-transitory memory storage module(s)) described above with respect to computer system 100 (FIG. 1). Exemplary web browsers can include (i) Firefox® by the Mozilla Organization of Mountain View, Calif., United States of America, (ii) Internet Explorer® by the Microsoft Corp. of Redmond, Wash., United States of America, (iii) Chrome™ by Google Inc. of Menlo Park, Calif., United States of America, (iv) Opera® by Opera Software of Oslo, Norway, and (v) Safari® by Apple Inc. of Cupertino, Calif., United States of America.

Meanwhile, in many embodiments, central computer system 301 also can be configured to communicate with one or more databases 312. The database can comprise a product database that contains information about products sold by a retailer. Database(s) 312 can be stored on one or more memory storage modules (e.g., non-transitory memory storage module(s)), which can be similar or identical to the one or more memory storage module(s) (e.g., non-transitory memory storage module(s)) described above with respect to computer system 100 (FIG. 1). Also, in some embodiments, for any particular database of database(s) 312, that particular database can be stored on a single memory storage module of the memory storage module(s) and/or the non-transitory memory storage module(s) storing database(s) 312 or it can be spread across multiple of the memory storage module(s) and/or non-transitory memory storage module(s) storing database(s) 312, depending on the size of the particular database and/or the storage capacity of the memory storage module(s) and/or non-transitory memory storage module(s).

In these or other embodiments, the memory storage module(s) of central computer system 300 can comprise some or all of the memory storage module(s) storing database(s) 312. In further embodiments, some of the memory storage module(s) storing database(s) 312 can be part of consumer computer systems 302 and/or one or more third-party computer systems (i.e., other than central computer system 301 and consumer computer systems 302), and in still further embodiments, all of the memory storage module(s) storing database(s) 312 can be part of consumer computer systems 302 and/or the third-party computer system(s). Like central computer system 301 and consumer computer system(s) 302, when applicable, each of the third-party computer system(s) can be similar or identical to computer system 100 (FIG. 1). Notably, the third-party computer systems are omitted from the drawings to better illustrate that database(s) 312 can be stored at memory storage module(s) of central computer system 301, consumer computer system(s) 302, and/or the third-party computer systems, depending on the manner in which system 300 is implemented.

Database(s) 312 each can comprise a structured (e.g., indexed) collection of data and can be managed by any suitable database management systems configured to define, create, query, organize, update, and manage database(s). Exemplary database management systems can include MySQL (Structured Query Language) Database, PostgreSQL Database, Microsoft SQL Server Database, Oracle Database, SAP (Systems, Applications, & Products) Database, and IBM DB2 Database.

Meanwhile, communication between central computer system 301, consumer computer system(s) 302 (e.g., consumer computer system 303), and/or database(s) 312 can be implemented using any suitable manner of wired and/or wireless communication. Accordingly, system 300 can comprise any software and/or hardware components configured to implement the wired and/or wireless communication. Further, the wired and/or wireless communication can be implemented using any one or any combination of wired and/or wireless communication network topologies (e.g., ring, line, tree, bus, mesh, star, daisy chain, hybrid, etc.) and/or protocols (e.g., personal area network (PAN) protocol(s), local area network (LAN) protocol(s), wide area network (WAN) protocol(s), cellular network protocol(s), powerline network protocol(s), etc.). Exemplary PAN protocol(s) can comprise Bluetooth, Zigbee, Wireless Universal Serial Bus (USB), Z-Wave, etc. Exemplary LAN and/or WAN protocol(s) can comprise Data Over Cable Service Interface Specification (DOCSIS), Institute of Electrical and Electronic Engineers (IEEE) 802.3 (also known as Ethernet), IEEE 802.11 (also known as WiFi), etc. Exemplary wireless cellular network protocol(s) can comprise Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Evolution-Data Optimized (EV-DO), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Digital Enhanced Cordless Telecommunications (DECT), Digital AMPS (IS-136/Time Division Multiple Access (TDMA)), Integrated Digital Enhanced Network (iDEN), Evolved High-Speed Packet Access (HSPA+), Long-Term Evolution (LTE), WiMAX, and the like. The specific communication software and/or hardware implemented can depend on the network topologies and/or protocols implemented, and vice versa. In many embodiments, exemplary communication hardware can comprise wired communication hardware including, for example, one or more data buses, such as, for example, universal serial bus(es), one or more networking cables, such as, for example, coaxial cable(s), optical fiber cable(s), and/or twisted pair cable(s), any other suitable data cable, etc. Further exemplary communication hardware can comprise wireless communication hardware including, for example, one or more radio transceivers, one or more infrared transceivers, etc. Additional exemplary communication hardware can comprise one or more networking components (e.g., modulator-demodulator components, gateway components, etc.)

For convenience, the functionality of system 300 is described herein as it relates particularly to consumer computer system 303 and a single consumer. But in many embodiments, the functionality of system 300 can be extended to each of consumer computer system(s) 302 and/or to multiple consumers. In these extended examples, in some embodiments, single consumers can interface (e.g., interact) with central computer system 301 with multiple consumer computer systems of consumer computer system(s) 302 (e.g., at different times). For example, a consumer could interface with central computer system 301 via a first consumer computer system (e.g., a desktop computer), such as, for example, when interfacing with central computer system 301 from home, and via a second consumer computer system (e.g., a mobile device), such as, for example, when interfacing with central computer system 301 away from home.

Electronic commerce (eCommerce) is a steadily growing portion of the retail sector. In 2014, eCommerce sales were over $300 billion. eCommerce sales have been growing with over ten percent growth rate each year for over a decade. As more and more products become available for sale to users over the Internet, the desire to manage the number of choices available to consumers becomes greater. In addition, as eCommerce sales continues to grow, there is a desire among eCommerce retailers to distinguish themselves from their competitors by providing a better experience for customers.

eCommerce sites typically provide a number of different methods by which a customer can find products. One method involves using search boxes, in which a user can enter search terms to find products for which they want additional information. Another method involves the use of filters.

A filter allows a customer to limit search results based on various attribute values.

An attribute is a feature of a product that describes a certain property of the product. Some examples of attributes can include brand, color, gender, material, title, description, and the like. An exemplary usage of a filter is in a navigation pane, such as one on the side of a browser page.

The manner in which a customer would use a filter is as follows. The customer is either browsing through a category, or enters a search term, for example, “running shoe.” Exemplary running shoes will be displayed to a user, typically in the center portion of a browser page or mobile app. A navigation pane can be displayed to the customer (typically on the left side of the screen in a browser implementation) showing some exemplary attributes. The customer can select various attributes. Thereafter, the products displayed to a customer will be limited to those that satisfy the selected attribute.

If the selected attribute was the color red, then the only products shown to the user would be those that have a red attribute flagged. If the selected attribute were a brand, only the products of that brand will be shown to the customer. The customer can limit the selections by price, color, size, and many other different attributes, depending on the type of item (e.g., color might not be applicable to food products, for example).

Another use for attributes is ad campaigns (also known as “product listing advertisements”.) An exemplary ad campaign utilizes search terms in a search engine (such as Google or Bing). When a user types in “Nike running shoe” in a search engine, there can be a sponsored ad featuring the eCommerce provider's link to various Nike running shoes. However, in order to run such an ad campaign, the eCommerce provider must be able to determine which products it has available that satisfy the search request. The accurate pairing of attributes with products also can be used to match newly added products with products that already exist in the eCommerce provider's database. There also can be regulations (either internal of the eCommerce provider or by a governmental entity) that requires certain attributes to be tracked (for example, unit pricing). It would be desirable to have a method for automatically populating various fields of various databases such that filtering can be used by the customers.

The problems encountered by missing attributes can be seen readily. For example, there can be a shirt made by company Z available in a variety of different colors. However, if the color attribute is not stored for that shirt, when a customer tries to filter a search request by color, those shirts do not show up, resulting in a potential missed sale by the eCommerce provider and a potential unhappy customer. Tests have shown a significant increase in impressions and clicks of items after attribute values have been added to the items.

A possible problem encountered by eCommerce providers is that the eCommerce provider must retrieve the attributes from a database accessible by the eCommerce provider. The database must be populated in some manner. The products being sold by the eCommerce provider might have a variety of different sources. The sources of the products typically might not provide entries for each potential data base entry for each product. Indeed, because different eCommerce providers might use different terminology and different database layouts, it might not be possible for a supplier to provide entries for each possible attribute in a database. In addition, some eCommerce providers allow third-parties to sell products using their site. In such a manner, the third-party might be tasked with populating the database entries that contain attributes that can be used for filtering.

An embodiment can operate by parsing the title of a product to determine various attributes about the product. For example, an eCommerce retailer may receive information about a product including the title. An exemplary title might be as follows: “Hewlett-Packard Smart Buy Pro Desktop 3.20 g 8 GB 500 GB.” From this title, various attribute fields can be completed such as brand (“Hewlett-Packard”), amount of RAM (“8 GB”), and the hard drive space of the computer (“500 GB”).

Thereafter, when a customer is browsing a website of the eCommerce provider, the customer can utilize filtering techniques to find the product he wants. Exemplary filtering techniques can include filtering search results by brand name, by amount of RAM, or by the size of hard drive. If the user wants a computer that has at least 800 Gigabytes (GB) of hard drive space, this particular entry will not be shown to the user. But the if user wants a computer that has at least 400 GB of hard drive space, this computer will be shown to the user after the user selects the appropriate filter(s).

There are various problems that must be addressed when analyzing product titles to find attributes. For example, some products do not have a brand in the title. So it cannot be assumed that the title will always contain a brand. In addition, product titles can contain acronyms, and the acronyms might not be consistently applied. In the example described above, there are two figures for GB, “8 GB,” and “500 GB.” An automated procedure must determine that one figure is for RAM and one figure is for a hard drive. In addition, some titles might not have a space between the number and the “GB.” Other products might not have a space (e.g., “8 GB”). Some titles might have capitalization and others might not. (e.g., GHz vs ghz). Some titles may abbreviate units of measurement, other titles may abbreviate units of measurement in a different manner (e.g., 21″ vs. 21 inches vs. 21 in.) Titles from one manufacturer can have a different structure than titles from another manufacturer. For example, a shirt from one manufacturer might have the color before the size while a different manufacturer might have the size listed before the color (e.g., “blue small shirt” vs “small blue shirt”). Other shirts might use abbreviations for sizes and others might not (e.g., “XL” vs “extra large”). Brand names may be expressed in different manners also (e.g., “Proctor and Gamble” vs. “Proctor & Gamble” vs. “Proctor&Gamble” vs. “P&G”). In addition, the brands being sold by an eCommerce retailer are not necessarily constant. An eCommerce retailer might begin selling a brand it had not previously sold before, or a new company might be in existence to sell a new type of product. It would be desirable to be able to detect and discover new brand names as well as extract known brand names with high precision and in a non-manual or automated manner.

FIG. 4 shows a flowchart illustrating the operation of a method 400 of determining a brand from a title. Method 400 is merely exemplary and is not limited to the embodiments presented herein. Method 400 can be employed in many different embodiments or examples not specifically depicted or described herein. In some embodiments, the procedures, the processes and/or the activities of method 400 can be performed in the order presented. In other embodiments, the procedures, the processes, and/or the activities of method 400 can be performed in any other suitable order. In still other embodiments, one or more of the procedures, the processes, and/or the activities of method 400 can be combined or skipped. In some embodiments, method 400 can be implemented by computer system 100 (FIG. 1).

An exemplary embodiment uses a sequence labeling algorithm to parse product titles to extract the brand attribute. It should be understood that a similar algorithm can be used to extract other attributes from the product title (such as color, size, and the like). After receiving the title, the title is divided into a sequence of tokens (block 402). These tokens can be determined by finding white-space in the title. For example, the title “Trademark Global 24 inch cushioned folding stool” can be separated into 7 different tokens, “Trademark,” “Global,” “24,” “inch,” “cushioned,” “folding,” and “stool.”

The tokenization can take place in a variety of different manners, both those already known in the art and those developed in the future. For example, each character in the title can be examined and compared to a delimiter character. In an embodiment using space delimiters, when a space character is detected, the previous characters are deemed to be one token, and the character after the space is the beginning of the subsequent token. Other delimiters can be used. This process can be iteratively performed for each character in the entire title, resulting in a set of tokens. Other information can be stored along with the token, such as an indication of the token's place within the title (e.g., 1^(st) token, 2^(nd) token, and the like).

The tokens are analyzed to determine which type of token it is (block 404). In an embodiment used to determine the brand name, this block can comprise determining if a token comprises the brand name of the item. The details of making this determination are presented in further detail below. It should be understood that, although this embodiment is discussed in conjunction with determining the brand of an item, other embodiments can determine other attributes of an item, such as screen size, amount of memory, color, and the like.

These tokens are encoded to associate each token in the series of tokens with a label (block 406). In some embodiments, the encoding might be through the use of a BIO encoding scheme, The encoding can be performed using one of a variety of different sequence labeling algorithms. Exemplary sequence labeling algorithms will be detailed below. A variety of different encoding schemes can be used. A BIO encoding scheme assigns a label to each token: B-brand, I-brand, or O-label. B-brand indicates the beginning of the brand name, and I-brand indicates an intermediate token (in other words, not the first token) of a brand name. O-label stands for “other,” meaning the token is not part of the brand name (in other words, the token is a part of a description portion of a title.) The difference between B-brand and I-brand can be determined during a training stage, explained in further detail below. For the exemplary title discussed above, “Trademark Global 24 inch cushioned folding stool,” the token “Trademark” is labeled as a B-brand, the token “Global” is labeled as I-brand, and each of the remaining tokens is labeled as “O-label.”

Thereafter, the encoded tokens are processed to determine a brand name. If the label of all tokens of a product is O-label, then it can be concluded that a brand name does not appear for that particular product, and the output label is “unbranded” (block 408). Otherwise, contiguous sub-sequences of tokens are analyzed to determine the brand name. A token with a B-brand label is located (block 410) and noted as the beginning of the brand name. Each subsequent token of the sequence of tokens with an I-brand label is then concatenated with the brand name (block 412). This concatenating ends either at the last token of the item or when a token associated with an “O-label” is found.

After each token of the sequence of tokens is processed, any token that represents a brand name is normalized to create a standardized representation of a brand-name (block 414). Here, various permutations of brand-name token sequences are stored in a normalization dictionary. Any token or token sequence that is in the normalization dictionary is assigned the normalized name.

In an embodiment using a key-value store type of database, the normalization dictionary might contain a key-value pair where the key is a brand-name variation and the value is the normalized brand name. Referenced above was a hypothetical product manufactured by Hewlett-Packard. Various ways of referring to the brand can be included in the normalization dictionary, followed by the normalized brand name. For example, the following key-value entries might exist:

{‘HewlettPackard’, ‘Hewlett-Packard’}

{‘HP’, ‘Hewlett-Packard’}

{‘Hewlettpackard’, ‘Hewlett-Packard’}

{‘H-P’, ‘Hewlett-Packard’}

{‘Hewlett Packard’, ‘Hewlett-Packard’}

Other variations of the name can also be present, along with capitalization variations. Any token with a value equal to one of those listed first in the key-value pairs listed above is replaced with the normalized token that is listed second in the pairs listed above. It should be understood that further variations can occur and might also be included in the normalization dictionary. Other variations can include capitalization variations and space variations.

Thereafter, the normalized tokens can be compared to a blacklist (block 416). A blacklist contains a list of terms that are known not to be brand names. A blacklist might contain terms that were processed and considered to be a brand name. The blacklist prevents further iterations of an embodiment from making the same erroneous determination.

Thereafter, a validation can be performed (block 418). A validation examines a term that is labeled as a brand but do not have a corresponding entry in a normalization dictionary. In other words, these tokens had never been previously found to be a brand. (In some embodiments, brand tokens that have an entry in a normalization dictionary are assumed to contain an actual brand name.) The validation can be performed manually or can be performed by an embodiment. After a run of an embodiment has been performed, tokens or token sequences that are predicted to be brand names are examined to determine if the tokens are actually brand names. If it is confirmed that the predicted brand name is accurate, the prediction is added to the normalization dictionary. Otherwise, the prediction is added to the blacklist. The confirmed and normalized brand name can be added to a database entry associated with the item (block 420).

The process of assigning a label to each token in a sequence can be termed “sequence labeling.” For example, as described above, sequence labeling can refer to assigning the labels “B-brand”, “I-brand”, and “O-labels” to each token in a sequence (such as a title). An input sequence X can comprise multiple tokens x₁, . . . , x_(m). A label sequence Y can comprise multiple elements y₁, . . . , y_(m). Each token x_(j) has an associated label y_(j).

A feature function can be defined in a variety of different manners. For example, given an input X, one can tokenize X and associate each token X with a label Y. If the input phrase is “The quick brown fox jumps over the lazy dog,” then the tokenized version is X={The, quick, brown, fox, jumps, over, the lazy, dog}. Each token in X is associated with a label Y. Y can be an arbitrary labeling scheme where Y defines the part of speech (DT=determiner, JJ=adjective, NN=noun, VB=verb, IN=preposition) of each word in X. Thus, given X (above), Y would equal {DT, JJ, JJ, NN, VB, IN, DT, JJ, NN}.

A feature function can be defined as follows:

${f\left( {x,y,i} \right)} = \left\{ \begin{matrix} \begin{matrix} {1\mspace{14mu}} \\ {0\mspace{14mu}} \end{matrix} & \begin{matrix} {{{if}\mspace{14mu} x_{i}} = {{{the}\mspace{14mu}{and}\mspace{14mu} y_{i}} = {DT}}} \\ {otherwise} \end{matrix} \end{matrix} \right.$

This feature function only returns a 1 for the 7^(th) xy pair and a zero for all other XY pairs. Thus ƒ(x, y, 2)=0 and ƒ(x, y, 7)=1.

In some embodiments, there are d feature functions ƒ₁, . . . , ƒ_(d). Define F_(i), a d-dimensional vector corresponding to the pair x, y, and position i, as follows: F _(i)=(ƒ(x,y,i), . . . ,ƒ_(d)(x,y,i)) Therefore, F(x,y)=Σ_(i=1) ^(m) F _(i)(x,y)

is a d-dimensional feature vector corresponding to the pair x, y.

Various different feature functions can be used. In some embodiments, a set of feature functions is selected, then tested to determine how effective the feature functions are. The selected set of feature functions can be tested by inputting all feature functions, then selectively turning off each feature to determine the effect each feature had on the precision of the analysis. In the end, the final set of feature functions is chosen such that removing any feature function would adversely affect the results. The resulting final set of feature functions represent characteristics of titles that can be indicative of an attribute, such as a brand name contained in a title.

The following is a list of feature functions that can be used in an embodiment that can be used to determine a brand name from a title:

A. Characteristic features:

1) The identity of the token;

2) The composition of the token (all numbers, alphanumeric, the presence of punctuation;

3) The case of the token (initial capitalization, all-caps, etc.);

4) Character n-gram suffixes and prefixes of the token; and

5) Number of characters in the token.

B. Locational features. These features are a function of the position of the token in the sequence of tokens into which the title is decomposed. These feature can include the following:

1) number of tokens in the title before the given token; and

2) number of tokens in the title after the given token.

C. Contextual features of tokens neighboring a given token. The features can include the following:

1) the preceding token;

2) the succeeding token;

3) the capitalization of the preceding/succeeding token;

4) whether both the token and the preceding token are capitalized;

5) whether both the token and the succeeding token are capitalized;

6) the bigram consisting of the token and the predecessor token;

7) the bigram consisting of the token and the succeeding token;

8) the bigrams consisting of the preceding two tokens and the successive two tokens;

9) whether the preceding/succeeding token are numeric;

10) whether the preceding token is contained in set: {“and”, “&”, “by”, “of”}; and

11) part of speech tag for the token.

D. Lexical membership. Here, each token can be checked to see if it already exists in a database containing brand names.

FIG. 6 shows a flowchart illustrating the operation of a method 600 of learning by using a training set. Method 600 is merely exemplary and is not limited to the embodiments presented herein. Method 600 can be employed in many different embodiments or examples not specifically depicted or described herein. In some embodiments, the procedures, the processes and/or the activities of method 600 can be performed in the order presented. In other embodiments, the procedures, the processes, and/or the activities of method 600 can be performed in any other suitable order. In still other embodiments, one or more of the procedures, the processes, and/or the activities of method 600 can be combined or skipped. In some embodiments, method 600 can be implemented by computer system 100 (FIG. 1).

In some embodiments, an algorithm such as that presented in method 400 will first be performed on a training database, which can be a set of titles with known brand information. Because method 400 is a learning algorithm, after method 400 has been performed on a training database, the results (the annotated tokens) can be compared to the tokens with the correct annotation. Method 400 learns which feature functions are typically present in brand names, such as the position of the token in the title, contextual features (e.g., consecutive tokens or the presence of conjunctions), parts of speech, capitalization, and the like. In addition, the normalization dictionary can be filled and validated such that method 400 can be subsequently used on a set of titles. In other embodiments, the normalization dictionary can be partially pre-filled using a set of standardized brand names with which extracted brand names can be compared.

A training database can be created (block 602). The entries in the training database can include a title and a brand. The title is divided into a series of tokens, using a technique such as described above (block 604). The tokenized titles are then encoded using the BIO scheme, and the titles are determined as described above (block 606). The tokenized titles are then compared to known brand names (block 608). This comparison can include analyzing the titles and the feature functions to determine characteristics of titles within feature functions. The feature functions can include those feature functions described above.

While methods 400 and 600 were described with respect to extracting brand names from titles, the techniques of method 400 can be used to extract other attributes from titles. Embodiments have been used to extract character names from titles (e.g., the character “Winnie the Pooh” from the product title “Disney Winnie the Pooh Feeder Bibs”) and attributes of electronic devices. For example, computers can be classified as to the amount of RAM, the hard drive space, or the screen size (of a monitor). The learning functions can learn how much RAM is typical in a computer and how much hard drive space is typical in a computer and can normalize units used to describe them (e.g, 1000 GB vs. 1 TB).

A variety of different algorithms can be used to assign labels to tokens. One type of algorithm that can be used for this process are sequence labeling algorithms. Sequence labeling can be treated as a set of independent classification tasks. In other words, each token can be assigned a label without regard to other tokens. However, the accuracy of such a process might be improved by making the label of a token dependent on the choices of nearby tokens. Thus, a special algorithm can be used to choose the globally best set of labels for the entire sequence of tokens at once.

One such algorithm that can be used is the structured perceptron learning algorithm. Assume a number of feature functions equal to d. A training set to the algorithm uses a set of labeled sequences {(x_(i), y_(i))}, where i=1, . . . , n. Each input x_(i) is a sequence of the form:

(x₁, . . . , x_(m))_(i)

With a corresponding sequence of labels:

(y₁, . . . , y_(m))_(i)

Such that the input sequence element x_(j) has a corresponding element y_(j). The labels belong to a finite set Y_(L). Let Ys denote the set of all sequences of length m such that each entry in the sequence belongs to Y_(L). Thus, |Y_(S)|=|Y_(L)|^(m). As an example, the algorithm presented in FIG. 5 can be performed to accomplish this task.

FIG. 5 presents pseudo code illustrating the steps of an exemplary structured perceptron algorithm. A weight vector is initialized to zero. Then a variety of iterations are performed. For each iteration, a predicted value of y is determined. This prediction can be performed using Vitterbi decoding or any similar type of algorithm. Once the iterations are completed, the weight for the feature functions is determined. In such a manner, the supervised learning algorithm can determine how much weight to give each feature function.

While the above described embodiment uses a structured perceptron algorithm to perform a sequence labeling algorithm, other sequence labeling algorithms or supervised learning algorithms also can be used. Exemplary sequence labeling algorithms can include the conditional random fields algorithm.

 15. The method of claim 9, wherein: the sequence labeling model is chosen from a structured perceptron algorithm or a conditional random fields algorithm.
 16. The method of claim 9, wherein: determining the type of each token of the sequence of tokens comprises: storing the first token of the sequence of tokens associated with the label B of the BIO encoding scheme as a beginning of a brand name token; concatenating to the brand name token of each subsequent token of the sequence of tokens that is associated with the label I of the BIO encoding scheme; comparing the brand name token to a blacklist database; changing a label of the first token when the brand name token is part of the blacklist database; wherein: the blacklist database comprises tokens that have been determined to not be the brand name; gathering each unique standardized representation of the brand name; determining a correctness of each unique standardized representation of the brand name; and when the standardized representation of the brand name is not correct, creating an entry in the normalization dictionary to reflect a correct standardized representation of the brand name, wherein the standardized representations comprise the standardized representation; and further wherein normalizing the attribute for each token of the sequence of tokens to create the standardized representations of the attribute for each token of the sequence of tokens further comprises: comparing the brand name token with a normalization dictionary to determine the standardized representation of the brand name; writing the standardized representation of the brand name to a database entry associated with the product; gathering each unique standardized representation of the brand name; determining the correctness of each unique standardized representation of the brand name; and when the standardized representation of the brand name is not correct, creating an entry in the normalization dictionary to reflect the correct standardized representation of the brand name.
